Question is in the title really. I didn’t mention that it is a game for android and ios. Currently have it working with basichttpbinding but really need to add some security and not sure what my options are.
Unity actually runs with version 2.6.3 of Mono, a cross-platform the .NET runtime which includes support for most of the core components. I’ve usually seen it compared to Microsoft’s .NET 3.5, give or take a bit. You’re probably best off looking up specific guides or comparisons if you have involved technical questions to research.
One major caveat: if you’re deploying to iOS, all of your code must be compiled ahead of time (“AOT”), which prevents you from using reflection or other dynamic behaviors, and tends to break some libraries you might want to use. It can also cause some complications for projects which make heavy use of generics.
